Specication of Letters Patent. Patented July 13, 1915.

Application led November 30, 1914; Serial No. 874,912.

T0 all whom it may concern Be it known that we, CHRISTOPHER OTTO- snN and HERBERT R. WRIGHT, citizens of the United States, and residents of Ottosen and Des Moines, in the counties of Humboldt and Polk and State of Iowa, respectively, have invented a new and useful Liner for Ice-Cream Cans, of which the following is a specification.

The object of our invention is to provide a cheap lining receptacle for ice cream cans and the like, made from a iieXible material adapted to be cut into suitable blanks, which can be shipped in flat form and may be readily folded and formed into a container for lining a can.

A further object is to provide sucha liner made from a blank so shaped and of such material that a receptacle may be formed with a circular flat bottom integrally connected with the side walls.

Still a further object is to produce such a lining so constructed that when the blank is properly folded to form the lining receptacle some of side walls will stand in such relation to the other side walls that the downward and outward pressure of the contents of the lining will press the side walls together and against the outer container wall to form tight joints. Y

Our invention consists in certain details, in the construction, combination and arrangement of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a perspective view of the blank from which our improved liner is formed. Fig. 2 shows a perspective view of the device in the process of completion, one end member having been folded into a vertical cylinder. Fig. 8 shows a perspective view of the completed liner, and Fig. 11 shows a vertical central sectional view through the ice cream can with the liner embodying our invention received therein.

Our improved liner for ice cream cans and the like is made from square sheets of suitable material, such as tough paper which has been treated to make it water proof and adapted to be readily cut and bent or folded. Out of the square sheets notches are cut in each corner as indicated by the reference numeral 10, lleaving the end members 11 and 12. Parallel slits are made at 13 and 14 in each side lof the sheet, the slits 13 and 1d extending inwardly from the sides of the sheet the same distance from the edges thereof to points spaced from the side edges of the sheet, as shown in Fig. 1. It will thus be seen that when said slits are cut the side members 15 and 16 are formed between the respective end members 11 and 12, and a portion 16 is left in the middle of the sheet which is integral with the end and side members. The width of the side members 15 and 16 is slightly less than the inner diameter of the completed liner designed to be made from the blank. The distancebetween the inner ends of the slit 14E and the inner ends of the member 15 is slightly less than the diameter of the inner end of the completed liner. The inner end of the slit 13 is the same as the inner end of the slit 14. In completing the liner one end member, for instance the member 11, is folded upwardly and its side edges are overlapped to complete a cylinder as shown in Fig. 2, having a bottom integral at one side of said bottom with said cylinder. The member 12 is then folded upwardly and its ends are overlapped so that the member 12 forms a second cylinder outside the rst cylinder and surrounding said first cylinder inclosing the joint in the side wall. The side members 15 and 16 are then folded upwardly to fit snugly against the outer cylinder hereinbefore described.

It will be seen that the completed device forms a cup or receptacle having vertical joints in its side walls. The joint, however, formed at the edge of the member 11 is closed by the member 12. The joints formed at the lower ends of the members 11 and 12 are closed by the members 15 and 16, so that when the completed liner is dropped into a cam 17 and pressed out against the sides and downwardly against the bottom of said can, and the liner is then filled with the liquid, said liquid tends to press the parts of the liner together to form a tight joint. By simply loosely fastening the parts of the liner together at the top it can be used as a water cup or the like. When, however, it is used within a rigid container such as the can 17, and is filled with liquid, the joints are so tightly pressed together that we have found by numerous experiments that the liquid does not pass through the liner to the can.

We preferably make the blank from which the liner is formed, of such size that when the liner is completed and placed in the ice cream can 17, the upper end of the liner extends slightly above the top of the can, where it serves as a handle, or it may be bent downwardly over the top of the ice cream can. `When it is desired to remove the liner, the upwardly extending edge can be grasped and the outwardly extending sides of the liner can be pressed together for pulling the liner away from the sides of the can 17, and the liner can be lifted upwardly. Owing to thevfact that the bottom of the cylindrical liner is formed integral with the said walls thereof, the liner can readily be removed without tearing it.

Our liner is of extremely simple and inexpensive construction, and owing to the peculiar form of the blank from which it is made and the way in which the blank is cut and folded to make the liner, we have been able to produce a cylindrical liner with the bottom integral with the liner. At the same time it is possible to ship the blanks after the notches 10 have been cut out and the slits 13 and 14: have been made, in the flat. Upon delivery the liners may be set up by the' user as they are required.

Applicants are aware that various forms of collapsible boxes have been made from pasteboard or the like, but believe their form of a liner, adapted to be shipped or stored in fiat form and to be readily and easily folded to form a cylindrical container or receptacle with the bottom formed integral with the sides, which receptacle is so folded as to cause all the edges to be practically sealed when the liner is placed in the can and filled with the liquid, to be new.

We claim as our invention:

1. A liner for ice cream cans and the like, comprising a flexible sheet, having an end piece folded into an upright cylinder over the central sheet, another end portion, folded into a second cylinder receiving the first, and opposite narrow side wings folded upwardly adjacent to opposite sides of said cylinders, so that said liner has a bottom integral with the end and side members, and the end members are arranged to press against each other to form a tight joint when the liner is placedv in an ice cream can and lled with a liquid.

2. A liner for ice cream cans, comprising a iiexible sheet, having parallel slits in its sides and having one end portion folded into an upright cylinder over the central portion of the sheet and the portion folded into another cylinder around the first cylinder, and having opposite side portions folded upwardly adjacent to the opposite sides of said cylinders so that the bottom of said liner is integral with the side and end members, and said side and end members are so arranged that all joints are covered, so that when said liner is placed in the receptacle and filled with the liquid the joints are all pressed together to make a liquid container.
